植物生长调节剂防落素P-51的合成及应用研究

Study on the Synthesis and Application of the Plant-growth Regulator-4-CPA P-51

本文报道了由对氯苯酚和氯乙酸在氯化钠存在下制备植物生长调节剂防落素P－51的中试方法，与传统方法相比，该法收率提高10％左右；向防落素中加入润湿剂和络合剂后制成的水剂，在大田试验，结果表明可使小麦增产11％左右。

This article studied the preparation of plant-growth regulator-4-CPA P-51 with P chlorophenol and chloroacetic acid under the control of sodium chloride. Compared with the traditional method, it can increase the yield to 10% also. By adding humectant and complexing agent into the p-51,the solution can raise the output of wheat about 11% in the open field.
